071 Česká Třebová

The Centre 071 in Česká Třebová has a long-time tradition of production and mounting of traction systems for railways and public city transportation. Another branch, in which the Company is active, is production and mounting of switchgear and control-gear assemblies and technological units, both for transportation (state railways, public city transportation, airports, suburb railways, metro), as well as for other branches (such as gas industry) or civil sector (switchgear and control-gear assemblies for power supply to shopping centres or office buildings). In parallel with this type of production, this centre produces elements of overhead contact lines. In addition to the above mentioned production program, this centre also includes a new logistics centre that provides material and technical supplies to the whole Company.
